Here's what we know so far of those aboard the Airbus when it crashed Thursday into the Mediterranean Sea on its way from Paris to Cairo.

They included 30 Egyptians, 15 French and two Canadians, as well as one person from the following countries: Algeria, Belgium, Chad, Iraq, Kuwait, Portugal, Saudi Arabia and Sudan. A British national on board the flight also has citizenship in Australia and Egypt.

Mohamed Shoukair

Shoukair, the plane's pilot, had 6,275 flying hours under his belt. And his family hoped that career was only the beginning.

"He had ambitions and dreams," uncle Shehab Shoukair said. "We thought he would one day be a member of Parliament."

As mourners paid condolences to the pilot's family at a Cairo mosque Sunday, loved ones described the 36-year-old as the family comedian, a role model and someone who brought people together.

His last conversation with officials on the ground was described by Greek air traffic control as light-hearted.

His Facebook page says he'd been with EgyptAir since 2004 and lived in Cairo.

"He loved to be a pilot. It was a major part of his life," Sameh Shoukair said. "He loved to be in EgyptAir."

Days before the crash, the pilot bought a piece of land, where he planned to build a house. His cousin had been pushing him to get married and arranged a blind date for him the day of the crash.

"We saw him as our child," Sameh Shoukair said. "It's difficult to now talk about him as dead."

Authorities say it's too soon to tell what caused the crash. But Saied Shoukair, the pilot's father, had harsh words for whoever's responsible.

"Whoever took away my only son," he said, "may God take the light of their eyes."

"i just can't believe this. I don't even know what to say. I feel like I am in a dream," said Tawfiq's 18-year old cousin, Maryam.
